At the global coordinate system,the flight velocity and flight angle of all the fragments are calculated with program.

Via finite element program, the parameters such as scattering velocity and scattering angle of premade fragment warhead are simulated.

Experiment research on angular spread characteristics in suburb environment

Through physics modeling,the spatial spread characteristic in the mutipath fastfading chnnel is introduced,and using the computer imitated results of typical parameter values in the typical environment,some conclusions about spatialangular spread characteristic are gained,and the shortages of the performance research about mobile channel are made up.

By isolating the central DOA and angular spread into decoupled parts,2-D joint searching can be simplified to sequential 1-D searching,which reduces computational complexity.
